When purchasing a replacement battery, it's important to be cautious and ensure that you're getting a genuine one. Here are a few ways to determine if a battery is original or not:
1. Buy from authorized sources: Purchase the battery from reputable sellers or authorized service centers. This way, you can be more confident that you're getting an original battery.
2. Check the packaging: Original batteries usually come in sealed packaging. Look for holographic seals, official logos, and correct spelling on the packaging. Counterfeit batteries often have poor quality packaging with spelling errors or blurry logos.
3. Verify the serial number: Some batteries have a unique serial number that can be verified with the manufacturer's website or customer service. Check if the battery you're considering has a valid serial number and verify it with the manufacturer.
4. Compare the physical appearance: Original batteries often have cleaner and more precise manufacturing compared to counterfeit ones. Look for any signs of poor quality, such as rough edges, uneven labels, or mismatched colors.
5. Compare the performance: One way to check if a battery is genuine is by observing its performance. Original batteries usually provide consistent and reliable power, whereas counterfeit batteries may have shorter battery life, inconsistent charge levels, or sudden drops in percentage, like the issue you mentioned.
In terms of whether it's better to pay a higher price to have a technician order the battery for you, it depends on your preferences and convenience. If you trust the technician and they have a good track record, it might be worth it to let them handle the purchase. However, if you prefer to buy the battery yourself, following the tips mentioned above can help you make an informed decision.
Remember, it's always important to prioritize safety when dealing with batteries. If you feel unsure or uncomfortable about the authenticity of a battery or the replacement process, it's recommended to seek professional assistance from authorized service centers or technicians.
